More specifically, enable AP-style beaconing on mesh ifaces, honor
FIF_OTHER_BSS filter and change the hw capabilities to reflect mesh
support.
Also enable IEEE80211_HW_SUPPORTS_PER_STA_GTK, IEEE80211_HW_MFP_CAPABLE
and WIPHY_FLAG_IBSS_RSN. Probably these should depend on the
capabilities of the hardware but I don't know which hardware supports
what.
These are required for secured mesh. We were able to establish secured mesh
links between two TL-WN821N cards with this patch.
